Regardless, no agent would allow his client to give up guaranteed money voluntarily. The guaranteed aspect of coaching contracts is where pacts highly differ from player deals.

It makes a good headline, but the real crux of Gruden's point is that he's not thinking about down the road. Instead the 54-year-old is focusing on turning the Raiders around quickly.

"Who guarantees I'm going to live 10 years?" he said. "So I don't think about that. You start thinking about a 10-year contract -- people don't know how it's structured and it doesn't matter. The only thing that matters is, 'Is Khalil Mack going to be here? Is Donald Penn going to be ready to play?' I've got more important things to worry about than eight years of my contract."

Gruden has enough questions to answer about his 2018 squad than worry about whether he's still around in 2025.
